  • We call the brain's internal capabilities Intelligence. It is convenient to

    give a similar name to all of the external influences, cultural or otherwise,

    that affect the evolution of the brain, and with it, the mind. We shall call

    these influences Extelligence. Mind is not just intelligence plus

    extelligence, its inside and outside, so to speak. Instead, mind is a feedback

    loop in which intelligence influences extelligence, extelligence influences

    intelligence, and the combination transcends the capabilities of both.
